It should be noted that the method provided by the embodiment of the present application for verifying data is generally held by server 101
Row, correspondingly, the device for verifying data is generally positioned in server 101.
It should be understood that the number of server, database in Fig. 1 is only schematical.According to needs are realized, can have
There are any number of server, database.
With continued reference to Fig. 2, it illustrates the processes according to one embodiment of the method for verifying data of the application
200.This be used for verify data method the following steps are included:
Step 201, the first data set and the second data set to be verified are obtained.
It in the present embodiment, can be first for verifying the executing subject (server 101 as shown in Figure 1) of the method for data
The first data set and second to be verified is obtained from local or other storage equipment in the way of wired connection or wireless connection
Data set.Wherein, data can refer to the storable various data of computer.Data can be number, text, character string etc..
Wherein, the data in the data and the second data set in the first data set correspond.Here corresponding relationship can
To refer to the correspondence of verification relationship.It should be appreciated that when the data in the first data set and the second data set are identical, the first number
It is identical with the data one-to-one correspondence in the second data set according to collecting.Therefore, it verifies the first data set and whether the second data set is identical,
Whether corresponding two data are identical substantially and in verifying the first data set and the second data set.
In some optional implementations of the present embodiment, the data in the first data set and the second data set be can be
The data record obtained from database.At this point, the first data set and the second data set can determine as follows:
Step 1 is inquired in first object database according to preset querying condition, the first note returned
Record collection, and according to querying condition, inquired in the second target database, the second record set returned.
In this step, querying condition can be arranged by technical staff previously according to specific application scenarios.Such as, it is desirable to
The data record of the first three days since current time is verified, then it is to start in current time on the date that querying condition, which can be set,
First three days within data record.Wherein, first object database and the second target database can be pre- by technical staff
It is first specified according to specific application scenarios.
Optionally, querying condition can also limit the field to be verified.Every data is recorded, institute can be only selected
It needs the field of part to be verified, to promote the flexibility of verification mode, while also contributing to promoting verification speed.
Step 2, in response to determining the number of the first record set record for including and the number of the second record set record for including
Mesh is identical, determines that the first record set as the first data set, and determines the second record set as the second data set.
In the first data set and identical the second data set, the number for the data that the first data set includes and the second data set
The number for the data for including should be also identical.Therefore, if according to identical querying condition in first object database and the second mesh
The number for the data record that the first record set and the second record set inquired respectively in mark database separately includes is inconsistent, then
First record set and the second record set are certainly different.Therefore, such case can first be filtered out.
Step 202, according to the first data set and the second data set, the first character trail and the second character trail are generated.
In this step, the character string that the first character string is concentrated includes the data in the first data set, the second character trail
In character string include the second data set in data, and the first character string concentrate character string and the second character string concentrate word
Symbol string corresponds, and the data that corresponding two character strings include are corresponded and put in order consistent.
In this way can will verification the first data set and the second data set whether same conversion be verification the first word
It accords with trail and whether the second character trail is identical.And verify the first character trail and the second character trail it is whether identical be verification
Whether the first character trail and the second character string concentrate corresponding character string identical.
It should be appreciated that putting in order for data in only corresponding two character strings is consistent, verification is just significant.
Otherwise, if inconsistent, the difference of the two character string greater probability that puts in order of the data in corresponding two character strings,
Also with regard to the appearance error checking of greater probability the case where.
Putting in order for the data that two character strings include can unanimously refer to corresponding data in the corresponding position of character string
Place.As an example, the first character string are as follows: " A1B1 ".Wherein, the first character string includes data " A1 " and " B1 ".Second character string
For " A2B2 ".Wherein, the second character string includes data " A2 " and " B2 ".Wherein, data " A1 " and data " A2 " are corresponding, data
" B1 " and data " B2 " are corresponding.So, putting in order for data is data " A1 " before data " B1 " in the first character string.By
In the second character string and data " A1 " corresponding data " A2 " are also before data " B2 " corresponding with data " B1 ".Cause
This, the data in the first character string are consistent with putting in order for the data in the second character string.If third character string is " B2A2 ",
Then the data in the first character string and the data in third character string put in order it is inconsistent.
In the present embodiment, the data in the first data set can be obtained the according to the preset successively splicing that puts in order
One character string, and determine the first character string as the first character trail；By the data in the second data set according to suitable with arrangement
The corresponding successively splicing that puts in order of sequence obtains the second character string, and determines the second character string as the second character trail.Its
In, putting in order for data can be specified by technical staff.
It is alternatively possible to which the data in the first data set are obtained the first character according to the preset successively splicing that puts in order
String, and the data in the second data set are obtained into the second character according to the successively splicing that puts in order corresponding with putting in order
String.Later, preset characters, and new first that will be obtained can be inserted between the every two data that the first character string includes
Character string is determined as the first character trail, and is inserted into preset characters between the every two data that the second character string includes, with
And obtained the second new character string is determined as the second character trail.
Wherein, preset characters can be by the preassigned character of technical staff.As an example, character includes but not in advance
Be limited to: "-", ", ", ", ", " * ", "+" etc..Preset characters can be used as the separator between two data of contiguous concatenation.
As an example, any character string " AB2B2C ".It include data " A ", " B2 ", " B ", " 2C " in the character string.?
It is inserted into after preset characters "-" between the every two data that the character string includes, obtaining the new character string is " A-B2-B-
2C”。
By being inserted into preset characters between the data of every two contiguous concatenation, can be very good to divide each data, from
And the case where including certain data in data set in the spliced character string of data for avoiding the occurrence of two contiguous concatenations.
With the above-mentioned character string " AB2B2C " including data " A ", " B2 ", " B ", " 2C " for example, preset characters are being not added
When, it in the character string " B2C " that is formed include " B2 " after data " B " and " 2C " splicing, the data " B2 " for being easy and including originally are mixed
Confuse, therefore, easily causes error checking in this case.And after having added preset characters, it can be using preset characters as number
Separator between, the case where to reduce error checking, to promote verification accuracy rate.
Step 203, it is based on the first character trail and the second character trail, determines whether are the first data set and the second data set
It is identical, and output is for indicating the first data set and the whether identical check results information of the second data set.
In the present embodiment, due in the first data set and identical the second data set, the first character trail and the second word
It is also identical to accord with trail.Therefore, can by verification the first character trail and the second character trail it is whether identical come judge first number
It is whether identical according to collection and the second data set.
It is utilizable existing each when it only includes a character string that the first character trail and the second character string, which are concentrated,
Kind character string method of calibration (such as cyclic redundancy check method, hash check) is to the first character trail and the second character trail
It is verified, to determine whether the first character trail and the second character trail are identical, and then determines the first data set and the second number
It is whether identical according to collecting.
Wherein, check results information can be any form of information.Check results information can be number, character, text
Word, image, video, signal etc..
It should be noted that in this application, two datasets to be verified, two datasets are divided for ease of description
It is not named as the first data set and the second data set, it will be appreciated by those skilled in the art that the therein first and second not structures
The particular determination of paired data collection.Similarly, above or below the first character trail, the second character trail, first object
Database, the second target database, the first record set, the second record set, the first character string, the second character string, the first hashed value
Collect, first and second that the second hashed value is concentrated also do not constitute particular determination.
The method provided by the above embodiment of the application verifies two by the corresponding character trail of two datasets
Whether a data set is identical.The data verified in two datasets one by one are compared, and help to promote verification speed.In addition, logical
The consistency of the data for guaranteeing that the character string that the corresponding character string of two datasets is concentrated includes to put in order is crossed, to subtract
It is few as data are not corresponding and caused by error checking the case where, to help to promote verification accuracy.
With further reference to Fig. 3, it illustrates the processes 300 of another embodiment of the method for verifying data.The use
In the process 300 of the method for verification data, comprising the following steps:
Step 301, the first data set and the second data set to be verified are obtained.
The specific implementation procedure of this step 301 can refer to the related description of the step 201 in Fig. 2 corresponding embodiment,
This is repeated no more.
Step 302, the first data set and the second data set are split as at least two data subsets respectively.
In this step, the data subset at least two data subsets of the first data set and the second data set be at least
Data subset in two data subsets corresponds, and the data that corresponding two data subsets include correspond.Change speech
It, is split as at least two data subsets according to corresponding fractionation mode for the first data set and the second data set respectively, to protect
It demonstrate,proves corresponding data and is belonging respectively to corresponding data subset.Specific fractionation mode can have technical staff to preset, can also
To be determined according to actual application demand.
Optionally, in the data that the first data set is in first object database, the second data set is the second target data
When data in library, the data in data subset at least two data subsets of the first data set belong to first object data
The data in data subset in the same record in library and at least two data subsets of the second data set belong to the second mesh
Mark the same record of database.
In other words, the first data set and the second data set are split according to record belonging to data.In the first data set and
When data in two data sets are the data record obtained from database, every data in database can be recorded and be made
For a data subset.
Step 303, for the data subset at least two data subsets of the first data set, according to the data subset,
Generate the first character string of the data subset；For the data subset at least two data subsets of the second data set, according to
The data subset generates the second character string of the data subset.
It in the present embodiment, can be by the number for the data subset at least two data subsets of the first data set
The first character string of the data subset is obtained according to the preset successively splicing that puts in order according to the data in subset.For the second number
It, can be by the data in the data subset according to suitable with preset arrangement according to the data subset at least two data subsets of collection
The corresponding successively splicing that puts in order of sequence obtains the second character string of the data subset.
Putting in order can be specified by technical staff.It should be appreciated that the data in data set are from database
When the data record of acquisition, puts in order and record putting in order for corresponding each field including every data, so that it is guaranteed that after
The corresponding data of continuous verification is meaningful, further avoid as order of the field is inconsistent and caused by error checking feelings
Condition.
It optionally, can be by the data subset for the data subset at least two data subsets of the first data set
In data obtain initial first character string of the data subset according to the preset successively splicing that puts in order, then initial the
It is inserted into preset characters between the every two data that one character string includes, and obtained new initial first character string is determined as
First character string of the data subset.It, can be with and for the data subset at least two data subsets of the second data set
Data in the data subset are obtained into the data subset according to the preset corresponding successively splicing that puts in order that puts in order
The second init string, and preset characters are inserted between the every two data that the second init string includes, and will
Obtained new initial second character string is determined as the second character string of the data subset.
Similarly with the step 202 in Fig. 2 corresponding embodiment, pre- by being inserted between the data of every two contiguous concatenation
If character, it can be very good to divide each data, thus in the spliced character string of the data for avoiding the occurrence of two contiguous concatenations
The case where including certain data in data set.
Step 304, corresponding first word of data subset at least two data subsets of the first data set is utilized
Symbol string forms the first character trail, and right respectively using the data subset at least two data subsets of the second data set
The second character string answered forms the second character trail.
Step 305, it is based on preset hash algorithm, the character string concentrated to the first character string is respectively processed, and is obtained
The corresponding first hashed value collection of first character trail, and it is based on hash algorithm, the character string that the second character string is concentrated is distinguished
It is handled, obtains the corresponding second hashed value collection of the second character trail.
In this step, hash algorithm can be specified by technical staff, and to the first character trail and the second character trail
In each character string handled, to obtain, each character string that the first character trail and the second character string are concentrated is corresponding to be dissipated
Train value.
Step 306, it is based on the first hashed value collection and the second hashed value collection, determines whether are the first data set and the second data set
It is identical.
In the present embodiment, since the character string that the first character trail and the second character string are concentrated corresponds, it obtains
To first hash the second hashed value of value set concentrate hashed value be also correspond.Therefore, can be respectively compared have pair
Whether the hashed value that should be related to is identical to determine whether the first data set and the second data set are identical.In the first data set and second
When data set is identical, two hashed values with corresponding relationship also should be identical.
It is alternatively possible to first determine the hashed value for the hashed value and the second hashed value concentration that the first hashed value is concentrated respectively
Total and/or total product；It is identical in response to the corresponding summation of determining first hashed value collection summation corresponding with the second hashed value collection, or
In response to determining that the corresponding total product of the first hashed value collection total product corresponding with the second hashed value collection is identical, the first data are determined
Collect identical with the second data set.
Wherein, due in the first data set and identical the second data set, each hashed value that the first hashed value is concentrated and
Each hashed value that second hashed value is concentrated corresponds identical.Therefore, the summation for each hashed value that the first hashed value is concentrated
It should be equal to the summation of each hashed value of the second hashed value concentration.The total product for each hashed value that first hashed value is concentrated is answered
This is equal to the total product for each hashed value that the second hashed value is concentrated.Therefore, what can be concentrated by the first hashed value is each scattered
Total and/or total product of each hashed value that total and/or total the second hashed value of sum of products of train value is concentrated determines the first data set
It is whether identical with the second data set.
This mode for calculating summation is compared with the method for comparing the correspondence hashed value that two hashed values are concentrated one by one, is calculated
The mode of summation does not need the corresponding relationship for spending time cost to determine hashed value again then.Because even dissipating in two hashed values
Putting in order for train value is not corresponding, but summation is determining, to further promote verification speed.
With continued reference to the signal that Fig. 4, Fig. 4 are according to the application scenarios of the method for verifying data of the present embodiment
Figure 40 0.In the application scenarios of Fig. 4, the first data set 402 to be verified can be first obtained from first database 401.Such as figure
Shown in, every data record in database 401 is corresponding with keyword and field 1.First data set 402 is including keyword
" K11 ", the value of field 1 is " F11 " and keyword is " K12 ", and the value of field 1 is that two datas of " F12 " record.
Likewise it is possible to obtain the second data set 404 to be verified from the second database 403.As shown in the figure, data
The same corresponding keyword of every data record and field 1 in library 403.Second data set 404 includes that keyword is " K21 ", word
The value of section 1 is " F21 " and keyword is " K22 ", and the value of field 1 is that two datas of " F22 " record.
Later, as shown in figure label 405, the first data set 402 can be split as two data subsets.Specifically,
Using each data record as a data subset.As shown in the figure, a data subset is { (K11, F11) }, second number
It is { (K12, F12) } according to subset.
Similarly, as shown in figure label 406, the second data set 404 can be split as two data subsets.Specifically
Ground, using each data record as a data subset.As shown in the figure, data subset is { (K21, F21) }, second
Data subset is { (K22, F22) }.
Later, for data subset { (K11, F11) }, taking for the keyword and field 1 in the data subset can be generated
Value is attached by character "-", to obtain corresponding first character string " K11-F11 " 407.Similarly, for data
Collecting { (K12, F12) }, the value that the keyword and field 1 in the data subset can be generated is attached by character "-", from
And obtain corresponding first character string " K12-F12 " 408.
Similarly, for data subset { (K21, F21) }, keyword in the data subset and field 1 can be generated
Value is attached by character "-", to obtain corresponding second character string " K21-F21 " 409.Similarly, for data
Subset { (K22, F22) }, the value that the keyword and field 1 in the data subset can be generated are attached by character "-",
To obtain corresponding second character string " K22-F22 " 410.
Wherein, the first character string " K11-F11 " 407 and the first character string " K12-F12 " 408 can form the first character string
Collection.Second character string " K21-F21 " 409 and the second character string " K22-F22 " 410 can form the second character trail.
Later, can use hash algorithm, respectively obtain the corresponding hashed value H11 of the first character string " K11-F11 " 407 and
First character string " K12-F12 ", 408 corresponding hashed value H12 (as shown in figure label 411 and 412).Utilize same Hash
Algorithm respectively obtains 410 pairs of the corresponding hashed value H21 of the second character string " K21-F21 " 409 and the second character string " K22-F22 "
